I bought a ST31000528AS around a month and a half ago. The drive was fine for the first month after which there were 17 bad sectors one day and two days later the total was 34 bad sectors. After the first 34 bad sectors appeared I used SeaTools to write zero to the entire disk, it turned up no more bad sectors. From then on there have been between 2 - 8 new bad sectors every couple of days, though the frequency of new bad sectors has decreased recently. Though there are now 62 bad sectors.
The computer has not moved from it's place on the desk since the harddrive was installed.
I would have returned it by now but the computer shop has been closed since before Christmas. I've been waiting around only being able to half use my computer in case I have to return the drive.
From my calculations it's possible to have 2560 bad sectors before the drive will fail the SMART analysis.
(40 bad sectors drops the normalized value by 1 out of a 100, the threshold is 36, so 100 - 36 = 64, and 64 sets of 40 bad sectors is 2560) Data is taken from Palimpsest.
Should I return the drive or just hope for the best?
How many bad sectors is acceptable to have on a harddrive?
Edit: I forgot to say thanks in advance as any help would be much appreciated. If anyone wants more information I'll be happy to supply it.

Bad sectors on a new drive is always unacceptable! So long as there is the possibility. RMA the drive.
They sound like Magnetic Bad Sectors however - so here's an alternative course of action:
Seeing that I'm in Jamaica, and shipping would cost perhaps.. just as much $ as it would take to buy a NEW drive..
I would Get and USE HDDREGEN.
This is a great bad sector removal tool, and it has the potential to completly rectify a drive.
If you dont want to RMA (for the sake of the chore of it)
Do run that program on your drive (let it "regenerate" all bad sectors).
Then, go ahead and use the drive, and see if those pesky sectors reappear.
Do this just for so long as you have the warranty (which is a good while I believe).
If they're magnetic - you CAN fix them, permanently with this program.
I'll be happy to help as you go along.

Well thanks for that piece of info, will come in handy at a later date.
I am returning the drive to the computer store today, phoned them and they said they will return it to their supplier (or Seagate I'm not sure). They are Seagate authorised resellers or something?
Currently doing a full erase, to see if there are any more bad sectors and to hopefully kill off any private data, not that there is really anything private on there.
It will cost around R30 on petrol to do this, considering the drive cost R1040 and HDDregen is around R400, so its all good, not that I could pay for HDDregen considering I dont have a credit card.
When I get the new drive I'm going to do a full erase as the first thing I do with it.
Just a question about HDDregen, does it only fix sectors once they are picked up as bad ones or can I get it to "fix" all sectors in the first place, before they go bad? The time it would take to do this might be a problem though, but I would do when I get the drive and might be able to get some one to pay for it for me, or maybe paypal or something.

I contacted Seagate support and got the following reply:
It is best if you exchange the drive now, you can do the exchange online at http://support.seagate.com/customer/warranty_valid
anything over 20 sectors is a neww to exchange
Not exactly sure because the English is a bit bad, but I think they said to return the drive if it has more than 20 bad sectors, which already done, should get the replacement this week sometime.
Can't wait, going to be awesome to not have to use a live cd.
